' In Germany September 9, 1937 1 Claim.

This invention relates to means for controlling a total-takingmechanism. In this controlling means, a manually operated member isprovided for all column totalizers, with the object of rendering activethe zero stop for the total taking from Ythe column totalizers.

In the known machines of this kind, a separate zero stop was providedfor each cross totalizer, for the total taking from the crosstotalizers, but such zero stops were selected in conformity with `themovement of the paper carriage, and were moved into active position bya. manually operated member provided for all zero stops. The zero stopin consideration was selected by means of the control plates arranged onthe column totalizers. In order to avoid the necessity of arrangingextra control plates, the-already present-adjustable control plate forthe species of Acalculation to be performed in the corresponding crosstotalizer, was employed for selecting the zero stop in consideration.This way of control, however, was possible only for complementarytotalizers, the control plate which had been adjusted for subtraction,selecting one of the zero stops when a positive value is Withdrawn, andthe control plate which had been adjusted for addition, selecting theother zero stop when a negative value is withdrawn. Selection iseffected by a rocking device which is permanently in operativeconnection with the manually operated y member aforesaid.

of the individual cross totalizers.

This, however, involved the drawback that when the total of a value wastaken from one of the cross totalizers, this same value could not besubtracted simultaneously from the other cross totalizers, or one of theother totalizers, because the zero-setting tooth of each cross totalizerwas in active position, and did not permit the setting to zero of thatcross totalizer' which it was desired to set to zero.

All these drawbacks are eliminated' according to the present inventionby allotting to each cross -parts are represented drawn totalizer, inmanner per se known. a separate zero stop which is selected, and movedinto active position, by a separate manually operated member allottedtoveach zero stop.

By these means, it is no longer necessary to provide an arrangement ofthe zero stops in complementary totalizers which is different from thatin normal cross totalizers, and so the manufacture of the-zero stops canbe standardised and the cost reduced, and the selection and operation ofthe zero stops are rendered reliable.

In the accompanying drawings, several constructional embodiments of theinvention are illustrated by way of example. The several embodimentshave been illustrated as adapted to a typewriting calculating machinebut it is understood that the invention is not limited to this, and maybe adapted tov any other suitable machine. l

General description of the machine The machine, in its fundamentalfeatures, comprises a machine frame I (Figs. 1 and 2) supporting thetypewriting mechanism and the paper carriage, not shown. Columntotalizers designated by the numerals 3 to 8, inclusive, are arranged ona totalizer suspension rail 2 (Fig. l) which is secured to the papercarriage. The column totalizers 3 and 8 may be dummies, since anaddition of the amounts in columns I and VI of the form 25 (Fig. 17) isnot required.

A calculating mechanism case, carrying a calculating mechanism isindicated generally by the numeral "9" and secured at the front side ofthe machine frame l.

At the right-hand front side of the machine, a table ID is secured tothe calculating mechanism case 9 and a slide II is mounted toreciprocate longitudinally in the table. Cross totalizers I2 and I3 areadjustably mounted on the table. During the operation of the machine,the cross totalizers I2 and I3 are moved by that column totalizer whichis in active position at the time. by a connecting rod I4 whose verticalrighthand end is attached to the slide I I.

Arranged in the frame of the machine is a typewriting keyboard I5, witha pair of changing over keys I6 and a carriage-return key I1.

A bearing frame IB on the machine frame I supports a calculatingkeyboard I9, a decimal tabulator keyboard 20, and the manually operatedtotal taking keys referred to in the introduction. The manually operatedmember for all column totalizers is the column-totalizer total-takingkey 2I whose key bar |39 is mounted to swing about a rod 90 (Fig. 3)secured in the bearing frame I I. The manually operated members forcontrolling the zero stops of theA cross totalizers, are thecrosstotalizer total-taking keys 22 and 23 which are alloted to thecross totalizers I2 and I3, respectively, with their respective key bars9| and I I'I also mounted to swing about the rod 90.

A motor 24 secured to the right-hand side of the machine frame Ioperates the drive of the machine.

The filling-in of the form The form 25 (Fig. 17) has six verticalcolumns, numbered I to VI, and on it is entered a record showing theconditions in a magazine on the rst and second days of October, 1937. Asshown in the first line of the form, and column I, the magazine had instock 167 kg. oi any material when it was opened on the irst October. 23kg. were supplied to the magazine, as noted in column 1I, and twocustomers, Messrs. I and II, bought 12 and i5 kg., respectively, columnsIII and IV. 'I'he total l delivery being 27 kg., column V, it had instock 163 kg. as noted in column VI, at the close of the iii-st October.A similar record was kept for the second October, showing a balance ofkg, in stock, column VI, and the values in columns II, III, IV and Vwere added.

The values to be booked in columns I and II o! the form 25, being "167and "23 in the present instance on the ilrst October, are introducedadditively and added at the' same time in the cross totalizer I3, making"190. The values in column II are added in the column totalizer l. Thevalues "12 and "15 which are to be entered in columns III and IV,respectively, are introduced additively may be selected for operation.

in the column totalizers and 0, and added in the cross totalzer is nowto be withdrawn from the cross totalizer I2 and at the same time to besubtracted from the value 190 in the cross totalizer I3, and at the sametime to be introduced in the column totalizer 1. This operation is 22allotted to the cross totalizer |2'. Due to the clear writing in thecross totalizer I2, the value 163 remains in the cross totalizer I3.This value is to be written clear from the cross totalizer I3 bydepressing thetotal takingkey 23. As it is not desired to add the valuesin column VI, the column totalizer 8 is a dummy. i

which is provided'with the key 22, has a projecagainst the rear side ofthe locking bar 94. A locking lever 95 is pivoted on 'the'left-hand sideof the key bar 9| about a screw 96 which holds the locking lever againstlateral displacement. 'I'he locking lever has an extension 96 which aspring 91 connecting the lever to the bar as a yielding connection.hol/ds against the front side of the locking bar 94, thusdeining theinitial position of the locking lever 95.

When the total-taking key 22 is depressed, its key bar 9| swingsclockwise about the rod 90. The key bar 9| is offset at |00 and its tailend 99 engages the lower end of a push rod |0| (Figs. 2 4). to shift therod in upward direction. The upper end |02 of the horizontal arm of thebellcrank 26 and turns the bell crank clockwise. Through the mechanismdescribed, the tooth 5 a on the zero stop 5| of the flap 4I is movedtowards the path of the zero setting teeth |6311 of the zero settingwheel |63 in the cross totalizer |2.

At its lower end, the push rod |0| is guided by a push rod |0| engagesthev mounted to swing at the inner side of the rimane described below inthe section a tongue ||8 at its upper end, for cooperation with thelower end of a forked link |55, as will be Operation upon depression ofthe cross totalizer total-taking key 22.

At its right-hand end, the bearing bridge m,

as shown in dotted lines Vin Fig. 1, is equipped with a lug |20,

which is secured to an angular bracket |22 on the bearing frame I8 byscrews |2|. At its left-hand end, the bridge is provided with a pair ofarms |23 and |24 (Figs. 2 and 3) whose outer ends are 1secured to thelocking bar 94 by screws |25. 4

The locking lever 95 partakes in the swinging movement of the total keybar 9| and therefore the lower end of its extension 90 engages in agroove |26 (Fig. 3, at the right) 'in the locking bar 94 under theaction of the spring 91, holding the lockinglever 95 and thetotal-taking key bar 9| in depressed position.

The total-taking key bar 9| while being depressed engages, with ashoulder |21 on its lower edge, a pin |30 which is riveted into theouter end of a double-armed lever |29. 'Ihis lever |29 is mounted toswing about a headed screw |3| (Figs. 2 and 3) at the` inner side of thefront l A pin |32 at the inner end of the double-armed lever |29 engagesin aslot |33 in the inner Yend of another double-armed lever |34 whichis also is fulcrumed about a headed screw |35. At its outer end,lthelever |34 is bent at right angles to screw |03 (Fig. 2) whichextends through a slot |04 in the lower end of the rod and is secured inthe frame of the machine, limiting, at the same time, the descent of therod by gravity and deilning its initial position. With its upper end.the push rod |0| slides in a slot |01 in an angular guide |05 (Figs. 1,2 and 4) which is secured to the casing 9' of the calculating mechanismby screws |05.

When the key bar 9| turns about the rod 90 f clockwise upon depressionof its key 22, the tail end |05 of its locking lever'95 engages belowthe tall end |99 of the crooked extension 'I I0 at the outer end of adouble-armed lever The lever is fulcrumed on a bridge ,I I3 (Figs. 2 and3) form a lug |36 which is arranged to engage a plate |31 at thefrontend of a double-armed lever |39. 'I'he lever |35 is mounted to swingabout the rod at the left of the total key bar |39 to which thecolumn-totalizer total-taking key 2| is secured, for total taking.fromthe co1- umn totalizers 4 tol, inclusive.

The total key bar |39 is also mounted to swing on the rod 90. A spring|40 tends to turn the clutch control lever |30 about the rod 90 inanti-clockwise direction so that its tail end I 4| engages a couplingmember |42. This coupling member controls the connection anddisconnection of a coupling element |43 including a cam |86 and a cam|61. withA respect to a continuously rotating drive shaft |44. A pinion|46 is keyed on the drive shaft |44 and the coupling member |42 isequipped with a tooth |65 at one end for` engaging between the teethvofthe pinion |46. A spring |64 tends to engage the tooth |65 with thepinion |46 and to connect the coupling element to the shaft |44 but isprevented from doing so while the tail I 4| of the clutch control lever|35 engages the coupling member |42.

When the total-taking key 22for the cross totalizer I2 is depressed, andits key bar 9| turns clockwise against the action of its spring 92 aboutthe rod 90, the locking lever ypartakes in this@ swinging movement underthe action of the spring 91. The extension 95 of the locking lever 95now slides down the front side of the locking bar 94 until the spring 91pulls the end of the extension into the groove |26 in the locking bar94A at the end oii the swinging movement. The totaltaking key bar 9| andits locking lever are held locking lever 35 rocks into locked positionits rear end |08 rocks the lateral extension |03 of the double-armedlever The tail end 33 of the total-taking key bar 3| shifts the push rodin upward direction, and the upper end |02 of the rod |0| (Fig. 4),strikes a lug |45 at the free end of the horizontal'bellcrank arm 26.The bellcrank is now turned i -clockwise and the mechanism to which itis connected isoperated, as described in section "The zero settingmechanism for the cross totalizer lz.

The shoulder taking key bar 3| acts on the pin |30 at the outer end ofthe double armed lever |23 and turns the lever clockwise about itsfulcrum screw |3|. 'I'his causes the other lever |34 to be turnedanticlockwise by the pin |32 about its iulcrum screw |35.' Its lug |36engages the plate |31 of the clutch control lever |38 and turns itclockwise about the rod 30 against the spring |40. The tail end |4| ofthe clutch control lever |38 now releases the coupling member |42 sothat its tooth |65 engages between the teeth of the pinion |46, so thatthe unit |43 is now connected to the pinion |46 and with the shaft |44which is continuously rotated by the motor 24. The pinion |46 is fixedwith the main shaft |44, while the cams |66, |61 are xed to one anotherand are rotatably mounted on the main shaft |44.

Now the cams |66, |61 participate in the rotational movement of the mainshaft |44. The cam |61 influences an unlocking slide |68 (Figs. 6, 7,8), the lower end of which is provided with a roll |68a guided on thecam |61. The roll |68a is permanently pressed against the cam |61 by twosprings |681) which act upon the unlocking slide. As the reducedperiphery of the cam |61 is presented to the roll |68a, the unlockingslide |63 moves downwards and acts with its incline |21 (Fig. 3) of thedepressed total its tail end |52. The upper end of the rod |53 is guidedin another slot |01a in the angular guide |05 (Fig. 4) and acts againsta lug 60a on the horizontal arm of the second bellcrank 60 describedheretofore in the section The zero stop mechanism for the crosstotalizer |3" whereby the tooth 82a on the zero stop 82 of the ilap 14is moved towards the path of the zero setting teeth |63b of the zerosetting wheel |63a in the cross totalizer I3.v

The second push rod |53 is slotted at its lower end and is guided by thescrew |03, as described for the first push rod |0 and its descent bygravity is limited by the slot. By these means, the second push rod |53is guided at its lowerl end and its upper end is guided by the slot |01ain the angular bracket |05 which, it will be remembered, is secured tothe casing 3 of the calculating mechanism by the screws |06.

When the key 23 is depressed and its keybar |41 is turned clockwiseabout the rod 30 (Fig. 3), a lug |50c on its locking lever |50 engagesbelow the tail end |03 of the extension ||0 at the right-hand end of thedouble-armed lever I||.

The lever is now turned anti-clockwise about its 324, (Fig. 7), upon thecontrolling ilap' 325 of.

the lever 321 mounted on the shaft326 (Figs. 5, 6, 9, 10) and rocks thelever-321 clockwise. 'I'he lever 321 lying against the lug 328 of thelever 323 which-is rigidly mounted on the shaft 326 participates in therocking movement of the lever 323, whereby the diierential mechanism andthrough the intermediary of the unlocking lever 333 and the member 33|the totalizers are unlocked. The effected rocking movement of the shaft326 is transmitted to the unlocking lever 335 by means of the parts 332,333, 334, 52 constituting a removable crank, whereby by means of themember 336 the cross footer |2 and by means of a further finger thecross footer |3 are unlocked.

The preparation for total Itaking from the cross The total-taking key 23for the cross totalizer I3 is arranged on its total-taking keyv bar |41(Fig. 3) at the right-hand side of the machine in the immediate vicinityof the total-taking. key 22 for the cross totalizer |2. which, asmentioned, is mounted to swing on the rod 30, is equipped with a steppedextension |43 which a. spring |48 holds against the rear side of thelocking bar 34. A locking lever |50 which is similar tothe locking lever35 of the key bar 3|, is fulcrumed on the key bar |41 at the left toswing about a screw |5|, but is held against lateral displacement. Thislocking lever has a depending, hooked extension |50b held by a springconnection |50a between the key bar |41 and the locking lever |50against the front side of the The key bar |41 fulcrum screw 2. Thelocking lever |50 partakes in the downward movement of the key bar |41and the spring |50a pulls the. extension |50b of the locking lever |50into the groove |26 in the locking bar 34, so that the locking leverl|50.

and the total-taking key barI |41 are held in depressed position. At thesame time, the shoulder |41a of the key bar |41 engages the pin |30 at'the outer end of the double-armed lever |23 and causes operation of. thelever |34 and |38, and

coupling of the unit A|43 with the shaft |44.l Now, the calculatingmechanism, 'the totalizers are unlocked as described.

The operation upon depression of' the crosstotalizer total-taking key 22ing lever 35 engages below the tail end |03 of thev double-armed leverandv the lever `is turned about its fulcrum screw ||2 in anticlockwisedirection. This swinging movement isl transmitted to the otherdouble-armed lever ||6 through the pn-and-slot connection ||4, ||5, andthis lever is turned clockwise about its fulcrum screw ||1. The lug I6at the tail lend of the double-armed lever ||6 moves upwards and engagesa forkshaped member |55 at the lower end of a link |56 under slightpressure.

At its upper end, the link |56, (Fig. 2), is pivoted to the free end ofan arm |51 by a screw |51a, whose other end is mounted to swing about ascrew |58 in the front wall 3|3 of the casing 3 of the calculatingmechanism (Fig. 2). A pawl |59 with an incline |50 at its free end, isfulcrumed on the arm I 51 and a spring |5|` is attached to the pawl atone end and anchored in an eye of the arm |51 at its other end. The pawl|53 therefore tends to bear against a check |62' on the arm |51. Aspring |13 which is connected
